Garage Door Garage Door Motor Replacement Affton, MO

Our Affton garage door motor replacement approach is shaped by Missouri's humid subtropical region, where hot, humid summers and short, mild winters, with frequent storms and moisture that lingers in the air most of the year. That context decides which springs, rollers, and seals actually last on your door.

Climate is half the story for a garage door in St. Louis County. Given hot, humid summers and short, mild winters, with frequent storms and moisture that lingers in the air most of the year, Affton doors wrestle with storm-season wind that stresses panels and bottom seals, corrosion that creeps across hardware in the muggy air, and summer heat and moisture that swell wood doors and seize rollers.

Nine out of ten Affton calls trace back to sagging insulated panels softened by repeated heat and humidity, storm-driven debris and water in the tracks, swollen, sticking wood doors in summer humidity, and pitted galvanized hardware on older doors. We pinpoint which one it is before quoting a cent.

Motor replacement is the right move when the opener's motor or gear assembly has failed but the rest of the unit (logic board, rail, sensors, remotes, wall console) is still in good shape. On a 6–9 year old LiftMaster or Genie, motor or gear replacement is typically 40–60% the cost of a full opener swap and gives you another 8–10 years of life. We carry motor and gear assemblies for the major brands and most models from the last 12 years.

Sizing matters. A motor sized for a light non-insulated 8x7 door will burn out fast on a heavy insulated 16x7. We size replacements by measured door weight: 1/2 HP for light residential, 3/4 HP for standard insulated, 1.25 HPS for heavy insulated or oversized doors. If the original opener was under-sized, we recommend an upgrade rather than matching the underspec original.

After motor replacement, we re-program travel limits, re-calibrate force settings, and verify auto-reverse on an obstruction test. The full visit takes 90–120 minutes including these checks. We include a 2-year parts and labor warranty on the motor replacement.

Signs you need garage door motor replacement

• Motor hums, door doesn't move

  Capacitor failure (cheaper fix) or motor windings (full motor needed). Diagnostic determines which.

• Burning smell during operation

  Stop using the opener — motor is overheating, possibly due to gear strip or under-sized motor on heavy door.

• Audible grinding from motor housing

  Gear assembly stripping or bearing failure. Continued use destroys the gear; immediate service preserves a $149 gear swap vs. a $349 motor replacement.

• Door moves slower than it used to

  Worn motor windings can deliver less torque, causing slow travel. Diagnostic confirms motor vs. unrelated issues.

• Smoke from motor housing

  Severe motor failure or wiring fault — unplug immediately and call for emergency service.

Common causes & what we fix

• Capacitor age

  Start capacitors dry out over 7–10 years and stop providing torque to the motor. Often misdiagnosed as motor failure. $25–$89 capacitor swap usually fixes.

• Gear assembly wear

  Nylon worm gears strip after years of cycles. The gear, not the motor, is failing — gear replacement is much cheaper than motor replacement.

• Motor winding burnout

  Genuine motor failure from over-load on heavy doors or sustained operation against an obstructed door. Replacement is the fix.

• Power surges

  Grid events damage motor electronics. Surge protection prevents the most common failures.

• Bearing failure

  Motor bearings fail at 12–15 years on average. Replacement is possible but often makes more sense as full motor swap.
